Hi team,

Does SN74CBTLV3257 support the use case for 10/100 BASE differential signal switching?

I think the electrical characteristics look OK.

Please let me know if you notice any care about for this use case.

Best regards,

100BASE-TX requires a cable rating of 100 MHz. The SN74CVTLV3257's datasheet does not specify a bandwidth. The website says 200 MHz, which might be enough, but I'd consider the SN74CB3Q3257 or TMUX1574 to be sure.

Hello,

I agree with Clemens on this topic.

In addition the bandwidth of these devices can support a 100MHZ signal.

This faq talks more about signal switches for higher bandwidth application and about signal switches for ethernet protocols applications.
